C# Dictionary（字典）的键、值排序

Dictionary<string, string> dic1 = new Dictionary<string, string>();

dic1.Add("ddd","123");
dic1.Add("aaa", "123");
dic1.Add("ccc", "123");
dic1.Add("fff", "123");
dic1.Add("eee", "123");
dic1.Add("bbb", "123");
Dictionary<string, string> dic1Asc = dic1.OrderBy(o => o.Key).ToDictionary(o => o.Key, p => p.Value);
Dictionary<string, string> dic1desc = dic1.OrderByDescending(o => o.Key).ToDictionary(o => o.Key, p => p.Value);

Dictionary<string, string> dic1Asc1
= (from d in dic1
orderby d.Key ascending
select d).ToDictionary(k => k.Key, v => v.Value);
Dictionary<string, string> dic1desc2
= (from d in dic1
orderby d.Key descending
select d).ToDictionary(k => k.Key, v => v.Value);

List<string> list = new List<string>();
list.Add("aaa");
list.Add("ddd");
list.Add("bbb");
list.Add("ccc");
list.Add("bbb");
var ascList = list.OrderBy(o => o);
var descList = list.OrderByDescending(o => o);

var ascList1 = (from l in list
orderby l ascending
select l).ToList();
var descList2 = (from l in list
orderby l descending
select l).ToList();
string str = "";
